APPLICATION FILED JAN. 29, 1915' Patented May 30, 1916.

L @3- if fiJflfi/Z Witne/ssesd Inventor I I Attorneys 4 JACOB 'r. .ronnson, or ATLANTA, enoneia LIGHT-FIXTURE;

Taall whom it may concern:

Be it known that I, citizen of the United States, residin at Atlanta, in the county of Fulton and tate of Georgia, have invented a new and useful Light-Fixture, of which the following is a specification.

The present invention appertains to fixtures for incandescent electric lamps or for other lights, and aims to provide a light fixture embodying a shade and holder therefor, the said parts having novel interengageable portions or means whereby the shade may be readily applied to and detached from the holder.

Another object of the invention is the provision of alight fixture embodying the shade and holder, each of which has integral means, whereby said means are cooperable' for readily applying the shade to and removing the same from the holder, and in order that set screws, clasps and similar independent securing elements need' not be employed. This provides a notable feature of the invention, in that, the shade and holder each embody but one part which reduces the complete fixture to but two parts, each of which is comparatively simple, substantial and inexpensive in construction.

It is also within the scope of the invention, to provide a fixture of that nature,

' which enables the shade to be conveniently applied to and removed from the holder, which enables the fixtures in bulk or quantities'to be compactly stored or boxed, and which renders the fixture serviceable, practical andeflicientin use.

. interen'gaging portions of the shade and I With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts .and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed'can be made within the scope of what isclaimed, without departing from the spirit of the invention.

The invention is illustrated in the accom-v drawings, wherein .panying e 1 is a perspective view illustrating Figur the holder and shade separated, a portion of.

the shade being broken away. Fig. 2 is a sectional view of a fixture illustrating the holder reversed. Fig. 3 is a perspective detail illustrating a.- modification.

In Fig. 1, there is illustrated Y PatentedMay 30,1916- "Application fi1edJ'anuary29, 1915. Serial No.5,069. i g

a holder V and shade 84. The holder 83 embodies an annular gallery or ring 85fhaving the upper v spider 86 for attaching it to a lamp 'or other support, and the lower-edge. "of-the gallery 85 is provided with inturned tongues 87 which are coiled and corrugated. The shade 84-is provided with anoutturned-annular flange 88 to enter the gallery 185, and-theflange 88 is provided-with recesses 89 for the passage of the'tongues 87,- the lower face ofthe flange 90, so that the corrugations of the tongues 87-and flange 88 are adapted to hold the 88 being corrugated, as at i shade against relative rotation with respect to the holder when thev shade is applied to the holder in the manner above indicated.-

Fig. 2 illustrates a reversal of the fixture illustrated in Fig. 1,in that the interengaging portions of the holder .91 and shade 92 are reversed. The holder '91 embodies the gallery 93 having the spider 94, and the lower tongues 95 which are bent outwardly are coiled and corrugated, the same as the tongues 87. The flange 96 of the shade 92 is turned inwardly, and is provided with recesses 97 forthe passage of the tongues 95, and the lower face of the flange 96 is corrugated, as at 98, to engage the corrugations of the tongues 95.

Fig. 3 illustrates the holder 61 provided I with a corrugated'ear 62 that. is not curled or bent back. This ear can be used either upon the exterior or lnterior of the holder,

and is engageable with the corrugated flange of the shade the same as the corrugated portions of the holder above described.

The interengageable corrugated portions of the shade and holder are of advantage since the shade can be held at various angular positions relative to the holder, and

when the shade is applied and turned relative to the holder, the corrugations of the two parts in moving over one another will cause the shade to vibrate and produce a series of clicks. This will enable the oper ator to conveniently and. effectively apply the shade to the holder, even in darkness, since the movement of the corrugations over one another will be perceptible to the sense of touch, and will inform the operator that the shade is being properly applied to the holder.

From the foregoing, taken in connection with the drawings, it is thought that the advantages and capabilities of the present invention will be apparent to those versed in the art, it being noted that the several forms of the invention have common and independent advantages due to the general and specific details of construction.

Having thus described the invention, What is claimed as new is:

1. A light fixture comprising a shade and holder therefor, one part having a flange provided With recesses, the other part having portions to pass through the recesses and bear against the flange, and the flange having corrugations between a pair of the recesses, one of said portions also having corrugations With which the corrugations of the flange are cooperable to limit the rela' tive rotation of the parts.

2. A light fixture comprising a shade and bolder therefor, the shade having a corrugated flange provided With recesses, and the holder having corrugated portions to pass through the said recesses and for holding said flange.

3. A shade having a flange provided With recesses, the flange having a series of corrugations between a pair of the recesses to cooperate With a corrugated portion of a holder.

4. A shade holder having corrugated p0rtions for the engagement of the corrugated flange of a shade.

5. A shade holder having coiled and cor- -rugated tongues for the engagement of the flange of a shade. v

6. A light fixture comprising a shade and holder therefor, the shade having a flange provided with recesses and corrugations, and

"the holder having coiled and corrugated tongues to pass through the said recesses and to support the flange, the corrugations of said tongues and flange being interengageable.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two Witnesses.
